ETI provides high-quality solutions for the complete overcurrent and overvoltage protection of applications in the field of photovoltaic and other renewable energy sources. Our products are designed for complete protection of: - DC circuits (overvoltage protection and reverse current protection) - circuits inside DC/AC inverters (semiconductor protection) - AC circuits between the inverter and the power grid (overvoltage, overcurrent and anti-islanding protection). The products are internationally certified and carry several quality marks.

DC - distribution and protection components Green protect - DC Introduction Photovoltaic systems are composed by photovoltaic panels, cables, fuses, switches, overvoltage arresters and power inverter. Photovoltaic panels utilise the power of sun light to converters photons to DC current. Electricity generated by solar panels is then fed into a power inverter that converts DC current to AC current. gPV fuse has been developed to protect cable and panel against "reverse" overcurrent. ETITEC B, C-PV series of over voltage surge protective devices has been developed to protect against direct and...

ETITEC B T12 PV series of overvoltage surge protective devices has been developed to protect against direct and indirect discharges and is intended to protect photovoltaic systems. The circuit topology consist of three varistors stages each protected by a thermal disconnection device. - optical indication of faulty device (green ok, red false) - remote signalisation (RC version only) - DIN rail mounting (EN 60715) - high discharge currents and high degree of protection - MOV varistor is the protective element - metal snapper, new way of mounting on DIN rail (easier, quicker) - modular design...
